8 Claims.

My invention relates in general to paper burster toys and more inparticular to a cane with mechanism for bursting paper with an explosivenoise. The present invention is more particularly an improvement overthe structure of one of my earlier patents-No. 1,004,043, issuedSeptember 26, 1911.

An object of the present invention is to provide an improved simplifiedpaper burster embodied in a cane having an elongated handle, and paperfeeding and bursting mechanism operated by exerting downward pressure onthe handle while holding such mechanism against a rigid surface such asthe floor, sidewalk, or the like.

A further object of my invention is the provision of a device of thischaracter having relatively few elements, substantially all of which arestamped out and of such configuration that may be quickly and easilymanufactured and assembled into a sturdy, eflicient, and attractive toy.

A still further object is the provision of a simplified and inexpensivecane type paper burster which will operate with a certainty and with arelatively small amount of pressure so that substantially any child,small or large, may satisfactorily operate the same.

One of the features of my invention is the provision of a simplified andsturdy mechanism with relatively few moving parts so that the devicewill operate satisfactorily and enjoy a long life under the most abusivetreatment.

Other objects and features of my invention will be apparent from thefollowing description taken with the drawings, in which:

Fig. l is a side elevation in reduced size of the cane device of myinvention.

Fig. 2 is an elevational view with one side of the housing removed, andwith the paper supporting, feeding and bursting mechanism incrosssection showing the piston and cylinder in the normal nonoperatingposition.

Fig. 3 is a side elevation of the operating mechanism of the device withone side of the housing removed, and the cylinder broken away to showthe position of the piston, at an intermediate position in itspaper-bursting stroke, and before the cylinder itself is moved in thehousing. The relative downward movement of the housing as between thepositions of Fig. 2 and Fig. 3 is readily apparent.

Fig. 4 is a fragmentary elevational view partly in section showing thefinal paper bursting position of the operating mechanism.

Fig. 5 is an elevational view of the operating mechanism in theoperating position of the structure of Fig. 1 turned through in acounterclockwise direction around a vertical axis.

Fig. 6 is an elevational View of the inside of one of the two identicalframe members.

Fig. '7 is a sectional view along the line l-'| of Fig. 6.

Fig. 8 is a detailed inside view of the stationary explosion head.

Fig. 9 is a detailed view of the combination paper support, paper feed,and cylinder closing unit.

Fig. 10 is a sectional view of the fastening structure for the two framemembers.

In the illustrated embodiment of my invention I provide an elongatedhandle 10 which may be provided in two parts, telescoping together at asleeve II rigidly secured on one portion of the handle for the readyreception of the other portion. With this structure the device may beconveniently packaged in a relatively short container, yet quicklyfitted together by any user, including a small child. The lower portion12 of the handle has rigidly secured thereto, a frame or a housing,including a pair of stamped-out identical frame members 13. Each framemember is provided with a laterally extending burr M on each of thesecuring apertures it along one side of such frame member. When theframe members are placed together in corresponding abutting relation,the burrs along one side of one frame member are inserted incorresponding apertures IS on what would be the opposite side of theother or corresponding frame member. When upset in the final assembly ofthe frame, the burrs 14 along one side extend in one direction and areupset on the opposite side of the corresponding frame member (Fig. 10),and the burrs on the other side of the frame extend away from theirintegral frame member [3 in an opposite direction. This is shownparticularly in Fig. 1 where the burrs l4 appear on the right-hand sideof the figure, while the burrs M on the left-hand side of the figureextend in the opposite direction and are upset on what would be in thatfigure, the back of the frame. This structure eliminates the necessityof separable rivets or other faswning means thus simplifying thestructure itself as well as the manufacture of the device. Inwardlyturned flanges ll on the frame members limit the downward movement ofthe handle, and the metal of the frame members themselves adjacent theapertures 18 in each member is peened to drive such metal directly intothe wooden handle and thereby rigidly secure such frame on the handle.

Each of the frame members l3 extend down through convex integralexplosion portions I9 and then through a cylinder carrying portion 2i toa cavity 22 which becomes a guide opening for the piston rod when thetwo frame members are secured together as shown in Figs. 1, 4 and 5,particularly.

The operating mechanism for the paper burster cane is entirely carriedby the housing including the two identical frame members Hi. Thisoperating mechanism includes a cylinder 23 slidably carried in theportion 2! of the frame. A piston rod 24, with a downwardly extendingstriker portion, is slidably supported in the cylinder 23 and retainedtherein by means of a friction cap 26 which may be driven into the lowerend of the cylinder. The friction cap as shown in Figs. 2 and 3particularly, comprises a one-piece stamped-out member having side walls2? tapering to such dimensions as to limit the distance to which the capmay be driven into the cylinder. A neck portion 28 is provided on thecap for receiving the piston rod 24 and maintaining the same, togetherwith the aperture 22 of the frame, in alignment in the cylinder andframe. The friction cap 26 prevents the piston from being removed fromthe cylinder and also acts as a stop for a coiled spring 29 surroundingthe piston rod 24 and extending between a washer 3! at the striking endof the piston rod and such cap. The washer 3! is retained againstrotation on the end of the piston rod by flattening the sides thereof asshown in Fig. 2 and is retained thereon by means of a striking pad 32which comprises a piece of very sturdy rubber tubing having an inneraperture 313 considerably smaller in size than the flattened end portion34 of the piston rod. By virtue of this difference in size, the piece oftubing 32 is frictionally retained on the end of the piston rod and willwithstand substantially any type of abuse in the operation of the toy.The striker pad 32 is slightly longer than the end portion 34 so thatsuch end portion will be maintained out of contact with the floor or thelike against which the cane is pressed.

The piston itself comprises a cup-shaped leather member 36 secured inthe top end of the piston rod 24 by means of an outside washer 3'! keyedto the end of the piston rod as shown in Fig. 2 and an inside washer 38similarly keyed to the piston rod and retained thereon by upsetting orpeening the end of such rod at 39. As will be noted from Fig. 2, thewasher 38 is smaller than the inside diameter of the piston cup 36, andthe washer 31 substantially the same diameter as the outside diameter ofthe leather piston. This assembly permits of the maximum flexibility ofthe leather piston itself, yet positively retains the same in positionin spite of the most rigorous use of the toy.

The upper end of the cylinder 23 as viewed in Fig. 2 is rolled to form aflange 4| while a onepiece paper holder plate 42 is provided with acorresponding aperture and downwardly extending flange which is foldedaround and pressed upon the flange 4| to rigidly secure the paper holderto the cylinder so that it moves therewith. A rubber grommet 43 issnapped into place at the cylinder opening and adapted to engage astationary explosion head 44 as will be presently explained. As to thepaper holder and feeding plate 42, this member together with thefastening means described above, and the feeding mechanism hereinafterdescribed is similar to the structure disclosed in my copendingapplication, Serial No. 123,661. The plate 42 includes a paper carryingportion with slots 343 for receiving paper feeding teeth with said slotsprovided in an angular extending portion 41 as shown particularly inFigs. 2, 3 and 9. The roll of paper 48 is pivotally carried on a movablehandle 49, integral with a mounting axis 5! non-removably secured in thearms 52 and 53 integral with the body portion of the plate i2 andslanting downwardly and outwardly away from such body portion. Thehandle portion 48 is slightly resilient and snaps into a notch 54 in thearm 53. The paper is fed from the roll 38 over the feed portion 4'! bymeans of a pivoted jaw 56 having downwardly extending teeth 57 andlaterally extending cars 58, the latter pivotally secured incorresponding apertures 59 in each frame member. An integral tail 6| isnotched at 62 to receive and retain a spring 63 secured under tension atone end around the pin 64, and bearing at the other end against the tailportion 6! as shown in Fig. 2. An embossed rib 66 extends from the bodyportion of the jaw upwardly through the tail for strengthening the jawmember as a whole and also acting substantially as a pocket for the endof the spring 63 as shown in Fig. 2.

As previously noted, an explosion head (Fig. 8)

is mounted by means of integral ears 61 in correspending slots 68 on theframe members. Although the explosion head is non-rotatably andnon-removably secured in the frame, there is a slight play thereinaxially of the cane by virtue of the width of the slot 6% and thicknessof the metal of the explosion head, so that the latter gives slightly asthe grommet 43 presses the paper 48 against the same on an explosionstroke. The head may be pushed up to lie flat against the flange 69 atthe top of the slot 68.

The assembly is completed with a retriever spring H extending from astamped-out ear 12 on the one-piece member 42 and an integral ear 73 onone of the frame members l3. As shown in Fig 1 only one of the ears I3is used in the assembly of the operating mechanism. With the two framemembers 53 identical, however, the extra ear [3 of necessity results,and although only one of the two members has mechanical function,together they balance up the frame from. an aesthetic standpoint.

As to the operation of the torpedo cane, the paper roll 48 is firstplaced on the handle and axis 49 with the end of the paper being fedacross the mouth of the cylinder grommet 43 and down intermediate thespring pressed jaw 56 and the paper supporting portion 41 on the member42. The rubber striking tip 32 is placed on the sidewalk, floor, or thelike and the handle is pushed downwardly. The spring 29 on the pistonrod 24 acts to normally hold the piston rod in its extended position andalso limit its movement in the cylinder 23. As pressure is exerted,however, the frame rigid on the handle It moves downwardly withreference to the piston rod 24 whereby the piston 36 moves upwardly inthe cylinder 23. In the meantime, the spring tension in the spring H andpossibly some slight friction between the outer surface of the cylinder23 and the wall of the frame portion 2! holds the cylinder stationarywith respect to the frame, and consequently in the position shown inFigs. 2 and 3. When the piston is moved approximately to the positionshown in Fig. 3 with reference to the cylinder, there is sufficientspring pressure built up in the coil spring 29, and bearing against theneck 28 of the cap 26 to force the cylinder upwardly. That is, thespring pressure causes movement between the cylinder and frame so thatthe cylinder occupies the position shown. in Fig. 4-, with the grommetd3 bearing against the paper 58 and the latter sealed against theembossed aperture portion 715 of the explosion head is. The aperture inthe explosion head, of course, registers with the aperture in thegrommet '33. On the balance of the downward movement of the handle, thepiston is moved rapidly to its uppermost position shown in Fig. l tothereby compress the air intermediate the cylinder and paper sealedacross the grommet to cause a bursting of such paper. As can beunderstood from an examination of Figs. 2 and 4, for instance, the paperis fed across the portion 41 of the paper supporting plate by means of apivoted jaw 56 on the downward movement of the handle, and consequentlythe compression stroke of the piston and cylinder. After the paper hasbeen bursted, the downward pressure is removed from the handle and thecoil spring 28 forces the piston rod outwardly while the retrievingspring ll pulls the cylinder to a position where the plate t2 engagesshoulders it on each of the two frame members it.

Although the assembly of the device is readily understood from the abovedescription. it might be explained that the piston and piston rodassembly is completed and then inserted in the cylinder 23. The cap maythen be pushed over the rod M from the bottom thereof and pressed intothe end of the cylinder in a tight frictional fit as shown in Fig. 3.The spring 29 is assembled on the piston rod and retained thereon by thewasher 3i and rubber striking tip- 32. All of the elements are assembledon one of the frame members is in a jig and then the corresponding framemember may be fastened thereto to retain all of the operating mechanismin or on the two-piece frame in a very sturdy fashion. The toy paperburster cane is, of course, harmless to operate and may be easilyoperated by any child. Because of its simplicity and ruggedness it willgive long and satisfactory service under all types of treatment.
